BOSTON -- Catholic groups in Boston have attacked a health club ad in January's issue of Boston magazine, which features nuns drawing a nude man, reporters said.

The ad "portrays a callous contempt for the sensibility of Catholics," Catholic Action League of Massachusetts member, C.J. Doyle told the newspaper.p>
